Overview
This lecture explains the threats posed by spyware and bloatware, including how they infect systems, their impact, and methods to detect and remove them.
Spyware: Definition and Risks
- Spyware is malware that secretly monitors activity on your system.
- It can display unwanted ads, steal personal data, or commit affiliate fraud using your purchases.
- Spyware is typically installed via peer-to-peer software, fake security apps, or malicious email links.
- It monitors your browsing habits and can send this data to an attacker’s server.
- Some spyware installs key loggers, capturing everything you type, including usernames and passwords.
- Collected data is sent to attackers, risking privacy and security.
Protecting Against Spyware
- Antivirus and antimalware software can often detect and block spyware.
- Only install software from trusted sources to reduce the risk of infection.
- Some spyware is hard to uninstall and embeds deeply into the operating system.
- Regularly back up your system to recover if malware is detected.
- Specialized removal tools like Malwarebytes can help find and remove stubborn spyware.
Bloatware: Issues and Management
- Bloatware refers to unnecessary applications pre-installed by device manufacturers.
- These apps take up storage, reduce system efficiency, and may have security vulnerabilities.
- Bloatware often benefits manufacturers financially but creates issues for users.
- Some bloatware can be uninstalled via the operating system’s app management.
- Occasionally, third-party uninstallers are needed to remove persistent bloatware.
